Malaysia has officially declared “null and void” its recently signed trade agreement with the Trump administration, a move triggered by Iran’s escalating control over the Strait of Hormuz and its demand for payment in Chinese Yuan for oil shipments. The decision marks a significant shift in the global financial landscape, potentially signaling the decline of the U.S. Dollar’s dominance in energy markets.
The foundation of U.S. Financial power since 1974 has rested on the “petrodollar” system – an agreement with Saudi Arabia stipulating that oil would be priced and traded exclusively in dollars. This arrangement compelled nations worldwide to hold substantial dollar reserves. Though, recent data indicates a weakening of this system. Between June 2024 and early 2026, the dollar’s share in global oil settlements has decreased by three to five percentage points, a trend now accelerating due to heightened geopolitical tensions.
The current crisis point is the Strait of Hormuz. Following U.S.-Israeli strikes against Iranian interests on February 28th, Iran effectively took control of the vital shipping lane, restricting passage to Western-linked vessels. The International Energy Agency (IEA) reports a drastic reduction in flow through the strait, resulting in the largest disruption to oil supply in market history.
However, Iran’s strategy extends beyond a physical blockade. On March 14th, Iranian officials announced a policy of “monetary weaponization”: tankers are permitted passage only if cargo is settled in Chinese Yuan. This announcement immediately strengthened the Yuan, reaching a rate of 6.84 to the dollar – its highest level in months.
For Asian economies, heavily reliant on Middle Eastern oil, the situation presents a stark economic reality. Approximately 80% of Asia’s oil imports transit the Strait of Hormuz. Countries like Vietnam, Pakistan, and Indonesia maintain strategic oil reserves sufficient for only 20 days. Facing potential industrial and transportation paralysis, these nations are increasingly compelled to accept Iran’s terms and utilize China’s digital payment platform, mBridge, to pay in Yuan. This shift transforms de-dollarization from a long-term political consideration into an immediate economic imperative.
China has been proactively building the infrastructure to facilitate this transition. The mBridge platform, now including Saudi Arabia and the United Arab Emirates, has already processed over $55 billion in transactions, with 95% denominated in digital Yuan. This system allows major Gulf producers to trade with Asia outside the SWIFT system and U.S. Oversight.
While Saudi Arabia has not formally abandoned the dollar, it has quietly established the technical capabilities to do so, including currency swap agreements with Beijing, joining mBridge, and ending its exclusive commitment to dollar-based pricing. The world now awaits the first nation to officially adopt Yuan-based oil settlements, a move that would signify the definitive collapse of the petrodollar architecture.
Financial analysts are monitoring three key indicators: the Yuan’s value, transaction volumes on mBridge, and Saudi Arabia’s position. Continued appreciation of the Yuan would confirm a substantial influx of capital into the latest oil settlement currency. An acceleration of transactions on mBridge in the first quarter of 2026 would demonstrate the platform’s capacity to handle global flows in real-time. Any Yuan-denominated settlement, even partial, from Saudi Arabia to China would be a definitive signal of a global power shift.
The petrodollar may not disappear overnight, but at the Strait of Hormuz, its position as the unchallenged reserve currency is eroding. Iran’s strategy, coupled with China’s economic power, is forcing a re-evaluation of a multipolar world where the U.S. Dollar no longer holds exclusive sway. This is not merely an energy crisis, but a fundamental reshaping of geopolitical power through currency.
